Questions : put the wrench down and went home.
 

hi guys !

Some of you may have seen my post in the build section, but my friend and I are building ourselves a miata each.
I have some questions for you guys, and I know some of you miata yodas out here know everything there is to know about everything, ever.

I'm the guy out of us 2 that's charged with doing the shopping and choosing the right parts for the cars so... I chose to go for a gt2560r by garrett.
Thing is, there are 2 types of 2560...

Garrett GT2560R-466541-1 (GT28R) Dual Ball Bearing Turbo w/Internal WG

and this one

Garrett GT2560R-466541-4 (GT28R) Dual Ball Bearing Turbo w/Internal WG

the main difference i found in between the two was some cast divider and inconel blades... which sounds nice but why are they priced the same?
Most importantly, which one should I purchase?

on to the second question :
When it's gonna come down to bolting up the exhaust manifold (you know, a turbo exhaust manifold)... should I put a gasket in there? and if so, which one to pick??

third one,
we were trying to do a timing belt job on our engines today, and shit happened.
We couldn't lock the camshafts in place when we removed the tensioners and a camshaft spun on both engines (yes).
Now, both engines are off timing and we still have to rotate the crank...
anybody has a procedure to re-time our engines and if we are to do this job ourselves, should we consider buying those fidanza cam gears??

fourth question :

where do you guys buy all your performance parts?? I know the main ones but if there is one you had a specific, memorable experience with (positive would be good) please say so!

fifth question :
my friend and me both removed our ac compressor and were wondering how much they were worth? (55 000kms)

I think that is about it for now ! please help me?

Search again (GOOGLE) for Miata timing belt replacement. There are pics of two wrenches in an "X" pattern with vice grips holding the wrenches in the correct place so the cams don't rotate.

thanks for the tip

So we managed to get the crank bolt off and remove the timing belt, but the crank rotated as we did so... Any tips on how to do the timing
Job???

I don't know, probably the first time someone has done a timing job on one of these. You're probably screwed.

No wonder you drive a pontiac

Google: miata timing belt

Plot twist: he doesn't.

Flyin Miata sells a Timing gear key for like $12. Its also a bottle opener..... and a keychain....
buy it....

:rofl: you betcha! Glad I could help :fawk:

See answers in bold

Are you seriously too stupid to figure out how to set timing on a bp?

Dear lord putting down the wrench and going home was probably a good idea.

Now stay home and don't pick up the wrench until you at least educate yourself on the most basic information on the planet.

Question 1 is a legitimate question, the others tell us you're a lazy n00b wanting to be spoon fed.

Thanks man! I got us some clamps to help us hold yhe cams in place too. Pulled the procedure at school to see which marks go where ! Ill just have to set the piston #1 up in compression at top and we'll see how it
Goes.

As far as the haters go, i just wanted to know if you had a special trick to help us do the job. But hey, jealousy's a bitch

Haters!



I'm struggling to figure out what i'm supposed to be jealous of.

Keep an eye on our build thread and you'll see

Thanks very useful on the go!

Wow I was all ready to be mad, but I'm not.


I wouldn't do much reading about Miatas if my boyfriend was as cute as yours either.

I'm struggling to decide if i care enough to go back and find your build thread.

Is your boyfriend cute, at least?

:laugh: oh yeah we're jealous of these barely mediocre na's hahaha

Be jealous of their Canadian-ness

and French-ness.

duh

So i pulled all the info out of alldata at school :) now just waiting on our waterpump and other stuff to come in and we'll start over friday night.

In for more of OP and boyfriend.

I have a special trick to help me get the job done but I'm not sharing her :)

In all seriousness, the special trick is Google. Heard of it?

I'm so jealous that you don't know how to change a timing belt :(
I wish I didn't know how to do that :facepalm:

^ :laugh:

ok so i bought me an NB miata
I plan on puttinng the head of the nb engine on the 94-97 block to have the outlets ready for the turbo.
Question is, which headgasket (na or nb) to use? or does it not matter?

Depends on what year NA and NB. The pre-vvt 1.8L BP all had the same headgasket (i believe). The vvt ones were re-designed to change the coolant flow.

:-\ I don't like to jump on the hate wagon, but I find it odd that you had trouble setting the timing of your car, but you just bought a whole 'nother car with the idea of pulling just the head off of it to put on a different car.. but you're not sure what headgasket you need. I would think swapping heads is something that requires a fair bit of technical knowledge in order to complete successfully, and "which head gasket" is probably fairly low on that list of knowledge needed.

the thing with automobiles and mechanics is that... anybody can do it, you just need to know how.
I happen to be very fortunate and have ressources around me that allow me to learn the skills and find the information I need to do the tasks.
Now as for specific jobs like the timing belt and the head swap, I figured I'd ask you guys since I thought the miata community was nice and knowledgeable, but I've been proven wrong, but then again... this is a forum and is not representative of all the real people out there who just want to enjoy their Miata and talk about them.
Back to the subject,
doing the head swap isn't that big of a deal, I have a longblock 94-97 just waiting in the shop, we have all the tools we need to do any job, all I need is the information, which I am slowly collecting (and isnt that complicated) this week to hopefully get it done next weekend.
As for the timing belt job, I KNOW how to do one, but I just wanted to know tricks from people that have done them in the past ON MIATAS, and know how to save time/energy. But that is just me, you're free to interpret my questions however you like, this is a free country.

And luckily for me, to go back to the gasket,
like the nice mister before me said, the 94-00 gaskets are the same. I have a 95 engine and and 99 engine so problem is solved,. I bought the headgasket today along with the intake gasket and throttle body gasket. Still waiting on the waterpump but we'll get it, and when we do, I'm pulling the engine and doing the swap (and the timing belt) :)

As for your lack of confidence iin our skills, I understand. I lack confidence in your skills too and that's something all mechanics do. deflate that ego and share the love.
Goodbye suckaz

and btw, we're building TWO separate cars, his in an NA , mine is the NB. I have an NA block which i'll use with my NB head, and his will just be a straight up replacement.

If you're doing all the work, I would spend a few bucks and go vvt. If my engine ever goes boom, or I need a new head for any reason, I can't see myself putting a non vvt head in--especially in an nb.

Thing is, althought we have a very good budget, the engine's that we have now are the engines that we're gonna use and there's not gonna be anymore money thrown in there. There's still a lot to be done and if there is money left over, we'll see what options we've got. But I don't think VVT is a good option financially for us at the moment. Especially if I do mine like that, he'll want his the same... twice the money
